Beam Failures
- Stringer Axial Stress
- Stringer compressive buckling
The Stinger Axial Stress is a simple method which calculates the Compressive/Tensile margin of safety as:
MS= [(Compressive Stress limit)*(section Area)/(Axial Force)] -1; (resp. Tensile Stress limit)
In the case of freebody sections, Axial Force is mapped to the freebody resultant Fx.
- : average axial stress as (Axial Force)/(Section’s area)
- : material compressive stress limit

- K_constraint = “constraint coefficient” on structural property. Def=0.0699
- : beam section’s radius of gyration
- E: material young’s modulus
